I'm an Oracle DBA who inherited 100 or so SQL Databases. I know how I
would accomplish this task in Oracle but I have no clue how to do it in
T-SQL. In short, I want to produce a comma delimited gantt type
timeline chart of my Backup Windows for import into Excel.
I'm not sure if this is the best place to get this information but I
found the msdb sysjobservers table which contains information about the
last run and duration of a job. It might be nice to get historical
information but I'm not sure where I'd find it. If there is a better
place to get this information then I'd like to know.
Here is the data I'm looking at...
use msdb
go
select j.name, s.last_run_outcome, s.last_run_date, s.last_run_time,
s.last_run_duration
from sysjobs j, sysjobservers s
where j.job_id = s.job_id
go
name last_run_outcome last_run_date last_run_time
last_run_duration
-- -- -- --

DB BACKUP1 1 20060406 200000 1958
DB BACKUP2 1 20060401 10000 5943
DB BACKUP3 1 20060402 30000 31934
(3 row(s) affected)
If I understand this correctly, the data shows backup1 last ran at
20:00 and ran for 1958 seconds or approx 33 minutes rounded up. I want
to kick out a comma delimited timeline showing the duration of the
backup. The first field is of course the name. The remaining 24
fields corrospond to the hours of the day 0 through 23.
So using the above data my output would look like this...
DB BACKUP1,,,,,,,,,,,,,,,,,,,,,X,,,
DB BACKUP2,,X,X,,,,,,,,,,,,,,,,,,,,,
DB BACKUP3,,,,X,X,X,X,X,X,X,X,X,,,,,,,,,,,,
BACKUP1 ran at 20:00 for less than an hour so there is one X in the
field corrosponding to the 20:00 hour showing the timeblock where the
backup ran.
BACKUP2 ran at 1:00 for less than 2 hours so there are X's in the
fields corrosponding to the 1:00 and 2:00 hours showing the timeblock
where the backup ran.
BACKUP3 ran at 3:00 for less than 9 hours so there are X's in the
fields corrosponding to the 3:00 through 11:00 hours showing the
timeblock where the backup ran.
I would greatly appreciate it if someone could help me with the T-SQL
to produce such a report.
Thanks in advance,

the output you want

You have 5 tables in msdb with historical information about backup. The name
of the tables all start
with backup. For instance, check out msdb.dbo.backupset.

yet another approach:
create function backup_mask(@.from_hour int, @.to_hour int)
returns varchar(26)
as
begin
declare @.idle_mask varchar(26)
declare @.busy_mask varchar(24)
set @.idle_mask = '('+replicate('_',24)+')'
set @.busy_mask = replicate('X',24)
return(
substring(@.idle_mask, 1, @.from_hour)+
substring(@.busy_mask, 1, @.to_hour - @.from_hour+1)+
substring(@.idle_mask, 2 + @.to_hour,25-@.to_hour))
end
go
-- unit test --
select dbo.backup_mask(1,5)
select dbo.backup_mask(3,15)
select dbo.backup_mask(1,24)
select dbo.backup_mask(19,24)

(1 row(s) affected)
(__XXXXXXXXXXXXX_________)
(1 row(s) affected)
(XXXXXXXXXXXXXXXXXXXXXXXX)

(__________________XXXXXX)

go
drop function backup_mask
go|||And another, using Alexander's function as a start,
just because we have QUOTENAME and STUFF.
(Note that the behavior of QUOTENAME when the
second parameter is '(' is not documented.)
create function backup_mask(@.from_hour int, @.to_hour int)
returns varchar(26)
as
begin
declare @.idle_mask varchar(26)
declare @.busy_mask varchar(24)
set @.idle_mask = replicate('_',24)
set @.busy_mask = replicate('X',24)
declare @.duration int
set @.duration = @.to_hour - @.from_hour + 1
if @.duration <= 0
return quotename(@.idle_mask,'(')
return
quotename(stuff(@.idle_mask,@.from_hour,@.d
uration,left(@.busy_mask,@.duration)),
'(')
end

to digest the information you've sent me and see what I can come up
with. Thanks again for the assist!
